Question

I'm stuck. How to parse Node with same name child node? In this example i need nodes with rate attribute.

<xml>
<Rates>
  <Rates winrate_cap="9999">
    <Rates rate="323"/>
    <Rates rate="343"/>
    <Rates rate="2338"/>
    <Rates rate="233"/>
  </Rates>
</Rates>
</xml>

My response wrapper class:

@Root(name = "xml", strict = false)
public class XMLResponse {

    @ElementList(entry = "Rates")
    public List<Rates> response;

    public static class Rates {

        @Attribute(name = "winrate_cap", required = false)
        public String winrate_cup;

        @ElementList(required = false, entry = "Rates")
        public List<Rates> rates;
    }

    public static class Rates {
        @Attribute(name = "rate", required = false)
        public String rate;
    }
}

You are on the right way. As you have many Rates here, better name the class more with more context and set the xml name via Annotation.

I've separated the XMLResponse and Rates classes, but this doesn't make any difference.

The class XMLRespone maps the <xml>...</xml> part:

@Root(name = "xml")
public class XMLRespone
{
    @Element(name = "Rates")
    private Rates rates;

    // ...
}

All types for <Rates...>...</Rates> is done by Rates class (and it's inner classes, which map the structure:

@Root(name = "Rates")
public class Rates
{
    @Element(name = "Rates")
    private RateList rates;

    // ...


    public static class RateList
    {
        @ElementList(entry = "Rates", inline = true)
        private ArrayList<RateValue> values;
        @Attribute(name = "winrate_cap", required = true)
        private int winrateCap;

        // ...
    }


    public static class RateValue
    {
        @Attribute(name = "rate", required = true)
        private int rate;

        // ...
    }

}

Deserializing your XML gives this output (using generated toString() ):

XMLRespone{rates=Rates{rates=RateList{values=[RateValue{rate=323}, RateValue{rate=343}, RateValue{rate=2338}, RateValue{rate=233}], winrateCap=9999}}}
